Canine bite wounds may cause severe underlying tissue trauma even with no clinically evident puncture wounds. In order to assess the ability of pre-operative diagnostic parameters to predict the extent of internal damage inflicted by a thoracic bite wound, the clinical, radiological and surgical data of 45 dogs that sustained thoracic bite trauma were recorded.
Clinical, radiographic and surgical parameters from 45 dogs of various breeds with thoracic bite trauma, were analysed (P<0.05). All dogs were treated according to a previously described protocol and had exploratory surgery including a thoracotomy.
Mainly small-breed dogs were traumatised. Clinical and radiological data were suggestive of internal trauma but not reliable as accurate indicators for internal lesions. Only radiological evidence of lung contusion was significantly associated with the presence of surgically confirmed lung contusion (P=0.006). Dogs with postoperative wound complications had a significantly higher risk of dying than those without complications (P=0.04).
This study concludes that according to protocol an optimal management of thoracic bite wounds in small dogs includes surgical exploration of the wound and the thoracic cavity in the presence of flail or pseudo-flail chest, fractured ribs, radiological evidence of lung contusion, pneumothorax or any combination of these.
犬咬伤伤口即使没有临床上明显的穿刺伤口，也可能导致严重的潜在组织创伤。为了评估术前诊断参数预测胸部咬伤伤口造成的内部损伤程度的能力，记录了45只遭受胸部咬伤创伤的犬的临床、放射学和手术数据。
分析了45只不同品种遭受胸部咬伤创伤的犬的临床、放射学和手术参数（P<0.05）。所有犬均按照先前描述的方案进行治疗，并接受了包括开胸术在内的探查手术。
主要是小型犬受到创伤。临床和放射学数据提示有内部创伤，但作为内部损伤的准确指标并不可靠。只有肺挫伤的放射学证据与手术证实的肺挫伤的存在显著相关（P=0.006）。术后有伤口并发症的犬死亡风险明显高于无并发症的犬（P=0.04）。
本研究得出结论，根据方案，对小型犬胸部咬伤伤口的最佳处理包括在存在连枷胸或假性连枷胸、肋骨骨折、肺挫伤的放射学证据、气胸或这些情况的任何组合时，对伤口和胸腔进行手术探查。
